Sofia mayor and leader of Bulgaria's center-right party 'GERB' (Citizens for European Development of Bulgaria) Boiko Borisov looks on during a news conference following parliamentary elections in the Bulgarian capital Sofia, Sunday, July 5, 2009. AP SOFIA, Bulgaria - Official results confirm Bulgaria's conservative opposition has won parliamentary elections by a wide margin.

Outgoing Socialist Prime Minister Sergei Stanishev conceded defeat hours after polls closed late Sunday, clearing the way for Sofia Mayor Boiko Borisov to form the next government.

The central election commission says results from 99.9 percent of ballots show Borisov's GERB Party won 39.7 percent and the Socialists garnered 17.7 percent.

It is still not clear if Borisov's party will have a majority of parliamentary seats to avoid having to form a coalition to govern. Election officials say the distribution of seats will be announced later this week.
